Patent EP-0474472-A1 (EP)
Inventor: FISHER ALMON P
IPC: B41J2/16
Filed: 1991-09-04
Abstract: A plurality of thermal ink jet printheads, each with nozzles (20) in a pre-cut nozzle face (21A), obtained from sectioning of an etched channel wafer (12) aligned and mated with a heater element (34) containing wafer (14) that have a patterned thick film layer (22) sandwiched therebetween. The printhead nozzles and nozzle face are produced in the channel wafer prior to the alignment and mating of the wafers by the combination of cutting a notch in the channel wafer through one end of a plurality of sets of etched channel grooves, forming the nozzles and the nozzle face in the channel wafer, and photodelineating the thick film layer on the heater element wafer, so that when the wafers are mated, the delineated edge of the thick film layer becomes part of the nozzles without requiring the cutting of the thick film layer by a dicing blade. In one embodiment, the heating element wafer has a similar notch (37) cut therein adjacent the delineated edge of the thick film layer prior to mating with the channel wafer. The two notches are confrontingly aligned, and the mated wafers are sectioned into separate printheads by cutting through the aligned notches, so that the blade remains spaced from the printhead nozzle face.

Abstract: In a process for recovery of CO₂ gas from a raw material mixed gas in which the CO₂ is recovered by absorption followed by vacuum desorption, water in the raw material mixed gas is removed by cooling the raw material mixed gas and passing it through a rotary dehumidification apparatus having a dehumidification chamber in which water in the raw material mixed gas is removed by a desiccant, and a regeneration chamber in which water is removed from the desiccant by heating the desiccant. Unadsorbed gas discharged from the CO₂ removal apparatus is heated and then used to heat the desiccant in the regeneration chamber.

Title: Reduction or prevention of skin irritation by drugs.
Inventor: CORMIER MICHEL J-N
IPC: A61K47/02
Filed: 1991-07-01
Abstract: The present invention provides a method of reducing or preventing skin irritation of a weak base drug by inhibiting the accumulation of the drug in the lysosomes. The drug is irritating to humans, i.e., the drug is susceptible to inducing skin or mucosa irritation in a human when the drug is transdermally administered to the human at a therapeutically effective rate. Irritation reduction or prevention is induced by coadministering to the skin or mucosa of the human: (a) a therapeutically effective amount of a weak base drug which is irritating to humans, at a therapeutically effective rate over a predetermined period of time; and (b) an effective amount of an agent capable of inhibiting the lysosomal uptake of the drug to reduce or prevent irritation to the skin or mucosa.

Abstract: A device for two-dimensional scanning of a surface by a light ray is described, which has a mirror (4) that can be rotated about two mutually perpendicular axes. One axis is an optical axis (A-A) along which the light ray emitted from a light source travels. The rotary movements of the mirror (4) are caused by two drive motors (1, 2), the rotary movement of the mirror about the axis (B-B) perpendicular to the optical axis (A-A) being performed via a differential gear (5). The differential gear (5) has two intermeshing gear wheels (10, 11). The mirror (4) is arranged in a mirror mount (3), which is connected to a hollow shaft, in a manner capable of rotation about the axis (B-B). One gear wheel (11) of the differential gear (5) is fastened to the mirror (4), and the other gear wheel (10) is connected to the drive shaft (12) of the first drive motor (1).

Abstract: Unique phase morphologies of incompatible thermoplastic polymers, including a higher melting temperature polymer and a lower melting temperature polymer that has been sufficiently chemically compatibilized to form a stable interface in a two-phase system, are achieved by pre-melting the higher melting temperature polymer, adding the compatibilized lower melting temperature polymer in solid form thereto, and thereafter melting the lower temperature polymer with mixing. In particular, in poly(ethylene vinyl alcohol)/modified polyolefin systems, compositions containing between about 35 and about 55 wt. percent EVOH are formed in which the poly(ethylene vinyl alcohol) exists as a continuous phase and the modified polyolefin exists as discrete domains dispersed therein. Such blended compositions have gas barrier properties comparable to homogeneous poly(ethylene vinyl alcohol).
